Let the other legs of the right triangle =
\n" ); document.write( "\"+a+\" and \"+b+\"
\n" ); document.write( "Let the altitude = \"+c+\"
\n" ); document.write( "------------------------------
\n" ); document.write( "One of the rt triangles:
\n" ); document.write( "(1) \"+8%5E2+%2B+c%5E2+=+a%5E2+\"
\n" ); document.write( "The other rt triangle:
\n" ); document.write( "(2) \"+18%5E2+%2B+c%5E2+=+b%5E2+\"
\n" ); document.write( "The original rt triangle:
\n" ); document.write( "(3) \"+a%5E2+%2B+b+%5E2+=+26%5E2+\"
\n" ); document.write( "---------------------------------
\n" ); document.write( "Plug (2) into (3)
\n" ); document.write( "(3) \"+a%5E2+%2B+18%5E2+%2B+c%5E2+=+26%5E2+\"
\n" ); document.write( "(3) \"+a%5E2+%2B+c%5E2+=+26%5E2+-+18%5E2+\"
\n" ); document.write( "(3) \"+a%5E2+%2B+c%5E2+=+676+-+324+\"
\n" ); document.write( "(3) \"+a%5E2+%2B+c%5E2+=+352+\"
\n" ); document.write( "and
\n" ); document.write( "(1) \"+a%5E2+-+c%5E2+=+64+\"
\n" ); document.write( "Add (1) and (3)
\n" ); document.write( "\"+2a%5E2+=+416++\"
\n" ); document.write( "\"+a%5E2+=+208+\"
\n" ); document.write( "and
\n" ); document.write( "(1) \"+8%5E2+%2B+c%5E2+=+a%5E2+\"
\n" ); document.write( "(1) \"+64+%2B+c%5E2+=+208+\"
\n" ); document.write( "(1) \"+c%5E2+=+208+-+64+\"
\n" ); document.write( "(1) \"+c%5E2+=+144+\"
\n" ); document.write( "(1) \"+c+=+12+\"
\n" ); document.write( "The altitude is 12 inches
\n" ); document.write( "-----------------------------
\n" ); document.write( "check:
\n" ); document.write( "(3) \"+a%5E2+%2B+b+%5E2+=+26%5E2+\"
\n" ); document.write( "(3) \"+208+%2B+b%5E2+=+676+\"
\n" ); document.write( "(3) \"+b%5E2+=+468+\"
